T041 1c]: 0122 it may concern lie it known that l, Fnnmnncn W. WILD, din. of the city of Baltimore and State of Improvements in Labelirig-Machines, of which the following is a specification.

This invention relates to a labeling machine adaptml to aiiix labels to cans which are provided with ears for the attachment thereto of a bail or handle; and it consists in means whereby the label is applied to one side of the can only, and centrally between the bail ears, as will hereinafter fully appear.

In the further description of the said invention which i'ollows, refercnce is made to the accompanying drawings, forming a part hereof, and in which,-

Figures 1 and 2 placed and to end, show an exterior side view of the improved labeling machine, and Figs. 3 and 4; when similarly placed, are a plan of the same. Figs. 5 and 6 placed end to end, show a longitudinal section of Figs. 1 and 2. Fig. 7 is an enlar ed partly sectional view of a portion of Fig. 3. Fig. 8 is a side view of a can the labeling of which is the function of the machine. Fig. 9 is a flat view of the label showlug its pasted surfaces and the spots where the hot qcement is applied. Fig. 10 is a, diagram to assist in the illustration of the invention as hereinafter described.

Referring'now to the drawings, 1, l are fiat horizontal bars forming the upper portion of the frame of the machine, and 2, 2 fixed horizontal narrow guide plates situated at the entrance end of the machine, between which the cans are pushed during the first part of the operation of the machine.

3, 3 are adjustable guide rods which are in efiect, continuations of theplates 2.

4c and 5 are transverse shafts journaled in brackets 6 which are bolted to the horizontal bars 1; and 7 and 9 sprocket wheels secured respectively to the said shafts.

10 is a sprocket chain carried by the sprocket wheels 7 and 9, and provided with carriers 11 which are properly spaced as shown particularly in Figs. 1. and 5.

In order to simplify the drawings this sprocket chain, as well as all others hereinafter described, are represented in side views of the machine by broken lines, the peculiar character of the chains appearing only on the plan views.

In order that the upper lay of thesprocket chain may not sag, to any appreciable extent, but be maintained in a practically straight line between its wheels, the lateral edges of the base plates 1) of the carriers 11 are made to enter and pass longitudinally of grooves 0 formed in the opposing edges of the supporting plates 12, which are best shown in Figs. 3 and 5.

The shaft 5 receives its rotation from the main driving shaft 13 which is supported by the standards 14 whose lower ends are bolted to the horizontal bars 1, through the medium of the sprocket wheels 15 and 17 and the sprocketchain 19.

The main driving shaft 13 is not driven directly from the motor not shown, but from a sheave 20 which rotates on a stud (Z and communicates its movement to the said shaft through the agency of any suitable gearing and clutch mechanism.

. 22 is an idle shaft similar to thedriving shaft 13, and like it supported by standards 23 which are bolted to the horizontal bars .1. The shafts 1.3 and 522 are each provided with a pair of pulleys to carry the conveyor belts 27 which are adapted to roll the cans for the greater part of their movement from the entrance to the delivery end of the machine.

29 and 30 are suitably supported horizontal bars to sustain the moving cans dur ing the entire labeling operation. The lower lay of each of the conveyor belts is deflected from a straight line between the pulleys 25, so as to press upon and insure the rolling of the cans, by means of the spring-held rollers 32.

By reference to Fig. 8 which is an exterior side view of acan to be labeled by means of the present machine, it will be seen that its body is cylindrical, and provided as before statec with two ears 7 which are on a dian1etriline, and that the label'is placed centrally between the ears on one side of the body.

Now, the main object oi. the present invention is to place the cans immediately upon entering the machine, in such a position that when rolled over the label to be afiixed thereto, a pbint centrally between th ears will. register with the center of the label. Toaccomfplish this result, I secure at a height above the angle bars 29 and 30 which is equal to the diameter of the cans, and directly inthe path of the ears f when a can is pushed forward by means of acarrier 11, a stop bar against the under side of which one of the ears of the can must come in contact. Should one of the ears of the can be in the position shown in Figs. 1 and 5, the advance of the ear in common with the can will. be stopped by its contact with the end of the stop bar, or to be more particular, with the end of a spring 36 secured to the bar which causes the can to be rotated in the direction indicated in Figs. 1 and 5 bycurved arrow, until the ear is sufficiently lowered to admit of its passing with the can under the stop bar. The can is thus placed and maintained in a certain position until the car passes from under the bar, when the can is freeto be rolled along the bars 29 and 30 by means of the conveyer belts, to and over the cement applying devices, and subsequently over the stack of labels, the upper one of which at that time has been provided with paste to effect its adhesion to the can body. It will be underv stood that While the can'is under-the stop bar, it is pressed upon by the lower 'lay of the conveyer belts which having a more rapid forward movement than the carrier, the can has'a tendency to rotate in the direc-.

.' .tion indicated by the-curved arrow in full lines and the ear is thereby held firmly in .j'contact with the stop bar until the end of "the said baris reached, when itis released and the conveyer-belts alone act on the can eviden gandwcgzuse it gto roll forward. It ,must be 'llnOWil fiS thecan-be 's to roll, the ear be:

that the position of the ears being ing clear of the stop er, it is a simple matterlto ascertain where the label should be placed to cause its center to register with a point central'betweenthe ears of the can.

In Figs. 2, 4 and 6 the transverse center line of the labelholder 37 is denoted by a dotted line y, and its distance from'the can as the same begins to roll after the detachment of the car from the stop bar'is suchthat the can will make one and a half rotations before registering with the label-in the manner before described,

By reference to Fig 10 which is a diagrammatic view to illustrate the points on the bed of the machine any one of which may serve as the center of thalabel to be applied to the'can, it will be seen that in the rolling of the can, the point 1 on the can which is central between the ears, will strike the table at 1", and that the point 2 on the can will come in contact with the point 2" of the table, consequently the distance of the center of the label or its holder from the point 1" which is central of the label holder 37, must be a multiple of one half the circumference of the can, to bring the label centrally between the ears f.

40 is a receptacle for cement which is liquefied by heat, and 41, 41 are disks or wheels partially submerged in the cement, with which the rolling cans come in contact and thereby receive dabs of cement which adapts them to subsequently pickup the upper label from the stack on the label holder.

The cement wheels'aic so placed with respect to the rear end of the stop bar, and the label holder, that the dabs of cement which have been applied to the can, will strike the label a short distance beyond its nearer edge, thus providing a space at the forward end of the label for the application thereto of paste, by means of a transversely moving endless belt 42 now to be described.

and 46 secured to and extending outwardly from one of the flat horizontal bars 1 (see Figs. 3 and 4) and receives an outer coating of paste from the paste pct 47. The shaft 43 also carries a second sheave 49 similar to the one 44 before referred to, which is provided with an endless belt 50 arranged to receive paste from a second paste pot 52. This second paste belt applies paste to the rear end of the label.

It will be understood that the lower lay ofeach of the paste belts 42 and 50 do not touch, but is slightly above the label, and the paste is applied by the rolling can pressing the belts into'contact with the label,

Thisnnode of applying paste is well known,

but in the present invention I go further and make the movement of the belts intermlttent, a stop in then motion occurring at the moment that the belts are pressed down by a can. By this arrangement the labels are never rubbed by a pasted surface and cannot therefore be wrinkled as is often the case when the belt is in motion at the time it 54 which drives another sprocket wheel 55 on a shaft 57 supported by brackets'under the bars 1, by means of a chain 59. The said sprocket wheels appear in Fig. 3, but the chain 59 is directly under one of the guide rods 3 and in consequence cannot be shown.

The shaft 43' before referred to, carries a tight beveled gear wheel 60 (see Figs. 1, 3 and 7) in mesh with a similar wheel (31. which is loose on a stud extending laterally from bracket 45. Formed as a part of the intense (7n the front end of the shaft'57 (see Fig.

1) a sprocket wheel 6i and around this wheel, and the idle wheel 66, is placed a sprocket chain 65 which is provided with three equally spaced pins 9 which project laterally from it; and in the operation of the unlchine these pins engage the pins e on the collar of the gear wheel 61, and cause it together with the miter wheel 61 to perform a part of a rotation. The arrangement of the various parts described is such, and the timing of their movements so regulated, that in the operation of the machine, a movement of the pasting belts only occnrswhen there is no can over them or in other words, a cessation of movement of the said belts when the cans are rolling over them. The shaft carryingthe cement wheels is driven from the shaft 57 by means oi the sheaves 67 and the crossed belt 69.

' In order that the intermittent movement of the paste belts may be uniform, the beveled gear (50 is, held tightly but yieldingly against the face ]2.' of thebracket 45 with which it is in. contact, by means'of a compressed coiled spring 70, upon the shaft d3. This arrangement of parts prevents the gear wheel 61 with its collar 62 being" moved by inertia toa greater extent-than that of looted by the engagement of the pins 9 on the sprocket'ehain, with the other pins e on. the collar of the wheel. 61.

It has been explained that the label is provided with posts at both its forward and rear ends; and that the dabs of cement on the can contact with. the label between the two pasted-surfaces, and near the for ward one. To make this clear ll show in Fig. 9 a fiat view of the label in which the forward and rear pasted surfaces are denoted by i and 7' respectively, and the points where the cement is applied, by is.

As the (ximented can lifts the label from the stack, it is evident that the pasted part 27 of the labelmust be drawn from under the pasting belt l2, and equally-as evident, that the said part'a' will be practically a loose pasted flap, which must be subsequently pressed down upon the can body.

Simply rolling the can over a fixed flat surface or bed will not effect a smooth adhesion of the forward end of the label to the can for the reason thatthe loose edge of the label will strike the bed which wrinkles or crimps it. ll therefore place a rotary brush 72 in the bed of the machine over which the can will roll, and by rotating the brush in the direction indicated by the curved arrow in Fig.6, the loose pasted flap is s oothly wiped down upon the can body.

The rear pasted end of a label is pressed in contact with the body as the can rolls over the rubber pad 73 in the usual manner.

The brush 72 receives its rotation from the shaft 57 through the agency of the shaft 75, the sprocket wheels 77, 79, 80 and 81, the last named being on the brush spindle, and the sprocket chains, 82 and 83. In order that the brush may rotate in the direction stated, it is necessary to employ gears m and n shown in Figs. 2 and 6 1n connection with the shaft 75.

The operation of the machine is as follows: A can rolling down the entrance runway 90 is caught by one ofthe carriers 11 on the sprocket chain and forced beneath the stop bar 35, and if there is no ear in the position shown in Figs. 1 and 5, the can without any change in its position is pushed forward until acted upon by the conveyor belts which rotate the can sufficiently to bring-r an ear in contact with the underside oi the stop bar. As soon as the can passes from under the stop bar it begins to roll and in passing over the cement wheels 41 Pro- 4 receives two 'dabs of that material. ceeding farther, it picks up the upper label from the stack of labels, which has previously been pasted, and after the ends of the label have been pressed down in the manner described, rolls down the delivery rim-way 92, in a finished condition, that is I to say with a label aiiixed centrally between 1. in a labeling machine, a andmeans to roll can longitudinally of the bed, and

the ears oi the body. v
